Toyotas single VVt requires 5W30 where’s as their dual VVt requires 0W20. Could I go with 5W30 in the dual VVt. Thanks.

Yes.
Thank you sir.

I recommend Mobil 1 EP HM 5W-30 or PUP 5W-30, both great oils. They both flow like a 0W-XX at cold temperatures.
No that's why it's a 5w and not a 0w

Did you know that the very first 5W-20 that Mobil introduced in 1974 was actually a 0W-20?
Did you know if it could pump a t 0F rating it would have to be labeled as a 0w rating

Not necessarily. They're both thin energy conserving oils. Mobil 1 EP HM 5W-30 is a PAO+mPAO+GTL blend, while PUP 5W-30 is all GTL.
Take a look at the PUP 5W-30 PDS bellow. There is enough room there to pass ASTM D5293 at -35C, guaranteed.
You can blab all you want if it meets a 0F rating it MUST be labeled as such
SAE J300 defines the W grades. 0W is defined as the CCS dynamic viscosity being 6200 cP or less at -35C (-31F). 5W is defined as the CCS dynamic viscosity being 6600 cP or less at -30C (-22F). 0W doesn't mean it's good to 0 degrees F. Most oil viscosity recommendation charts in OMs show that 5W-xx can be used below 0F, maybe down to -20F. Would have to look at each vehicle manufacter's recommendation that lists more than one viscosity because some manufactuers will be conservative and cut back the low temp from the miniums defined by J300 - ie, they may say the minimum cold temp for 5W-xx is -10F instead of -20F.
The 2015 verson of J300 shown below is the latest version, it hasn't been updated since 2015.

You made your point more than once, we got it.
It better be at least for the W grade rating, or else the Earth is flat.Da*n it 15W40 is actually thicker then 0/5-W40
My statement should have been a 0W rating not F typing fast and busy

I was reffering to HTHS being 3.7 instead of 3.5.
Higher winter grade is not thicker in my book. Atleast not useful thickness.
Just reading what people type without having ESP.
Higher W grade is certainly a concern in cold start-up weather, so it shouldn't be ignored. At the same cold temp, a 15W is certainly thicker than lower W rated oils. There's a reason that the W grade was invented and defined by SAE J300. Even two xW-40 oil grades can have different KV100 or HTHS viscosity since the grades are ranges, not specific numbers. Plus, the HTHS viscosity can be effected by the VII package in the oil, as the level and kind of VIs can effect the temporary oil viscosity under high shear rates.
Yeah but who runs their engine cold for more then 10min?
10W40 is not usefully thicker then 0W40. Could argue 15W40 is with slightly higher min. HTHS.
All good certs has stay in grade requirements VII is a non issue.

10 minutes of engine running after a very cold start-up using the wrong W grade isn't doing your engine any favors, and could lead to excess start-up wear.
10W-40 is not usually thicker than 0W-40 at cold temps? Is that what you're saying? If so, that's not true. A 10W will be thicker at the same cold temp than a 0W. A 0W made it to the 0W grade for a reason. Talking about W grades and KV100 and HTHS viscosity are all different discussions.
No im saying there is no benefit to 10W40 over 0W40.
